情态动词专项练习及答案详解
情态动词专项练习及答案详解一、单项选择情态动词1．—Tony _______ what I did annoying though he didn’t say anything.—So you think you will have to make an apology?A．could find B．should have foundC．might find D．must have found【答案】D【解析】【详解】考查情态动词+have done。
句意：—Tony一定觉得我做的事很烦人，尽管他什么也没说。
—所以你认为你得道歉吗?。
由“what I did”可知，此处是对过去事情有把握的推测，must have done“一定是做某事了”。
故选D项。
【点睛】情态动词+ have done结构：1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句.如：It must have rained last night,for the ground is wet.2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定.can和could一般用于否定句和疑问句,could的语气较can弱.如：He can't have finished the work so soon.3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could.如：They may not have known it beforehand.4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如：I needn't have bought so much wine—only five people came.5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些.如：You ought to / should have studied harder.你本应该更努力学习的.（但没有）He oughtn't to / shouldn't have done that.他本来就不该做那件事.（可是做了）6.“would ＋ have ＋过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意.如：I guess the poet would have been about twenty when she wrote her first poem.Another worker wouldn't have acted like that.分析句子可知，由“what I did”可知，此处是对过去事情有把握的推测，must have done“一定是做某事了”。

4．—I wonder if this smart phone is Mary's.—It _______ belong to her. _______ is totally different from this one.A. mustn't; HerB. can't; HerC. can't; HersD. may; Hers 【答案】C【解析】【分析】句意：――我想知道这个智能机是否是玛丽的。
――不可能属于她，她的和这个完全不同。
情态动词表示推测时，用must表示“一定”，用might, could表示“可能”，用can't表示“不可能”。
从句意看，这手机与她的完全不同，故不可能是她的，前面用can't。
